Preparation method of dental zirconia pre-sintered body and zirconia pre-sintered body and manufacturing method of zirconia ceramic using same

摘要

PURPOSE: A producing method of a zirconia pre-sintered body for prosthesis, the zirconia pre-sintered body, and a producing method of zirconia ceramics using thereof are provided to improve the aesthetics with the similar color with the personal teeth color. CONSTITUTION: A producing method of a zirconia pre-sintered body for prosthesis comprises the following steps: compress-molding zirconia powder, after inputting into a die; inserting a rubber mold containing the molded zirconia block into a mold filled with oil, and pressurizing the oil for secondly molding; sintering the molded zirconia block at 950~1,100deg C; and cooling the sintered zirconia block.
